Question

If curcumference is one inch, what is the diameter ?

Answer 1

If you really need to ask that question then your parents ought to complain to the school where you should have been taught basic things such as this.

What DO they teach in schools nowadays?

Answer 2

c=pi(r)squared

you do the math.

d=r x2

Answer 3

1/pi

Answer 4

.318

1/pi

She's thinking of area.

The area of a circle is pi x (r squared)

Answer 5

Use the formula:

   circumference = pi x diameter

Put into the formula what you know from the question:

      1 inch          = 3.1416 x d

       1/(3.1416)   = d.

Now just divide 1 by 3.1416 and you'll have the answer.

        0.318         = d.                

        

Answer 6

2*pi*r = Circumference

with r the radius.

2*pi*r = d*pi

with d the diameter since diameter = 2*radius

So circumference = d*pi

Diameter = d = circumference/pi.
